Giant and accessible conductivity of charged domain walls in lithium niobate
Christoph S. Werner, Simon J. Herr, Karsten Buse +4
Ferroelectric domain walls are nm-sized interfaces between sections of different allowed values of the spontaneous polarization, the so-called domains. These walls - neutral or cha…
Electrostatic topology of ferroelectric domains in YMnO
Tobias Jungk, Ákos Hoffmann, Manfred Fiebig +1
Trimerization-polarization domains in ferroelectric hexagonal YMnO were resolved in all three spatial dimensions by piezoresponse force microscopy. Their topology is dominated…
Low-voltage nanodomain writing in He-implanted lithium niobate crystals
M. Lilienblum, A. Ofan, Á. Hoffmann +6
A scanning force microscope tip is used to write ferroelectric domains in He-implanted single-crystal lithium niobate and subsequently probe them by piezoresponse force microscopy.…
Quantitative measurement of the surface charge density
Florian Johann, Elisabeth Soergel
We present a method of measuring the charge density on dielectric surfaces. Similar to electrostatic force microscopy we record the electrostatic interaction between the probe and…
Lateral Signals in Piezoresponse Force Microscopy at Domain Boundaries of Ferroelectric Crystals
Florian Johann, Tobias Jungk, Martin Lilienblum +2
In piezoresponse force microscopy a lateral signal at the domain boundaries is occasionally observed. In recent years, a couple of experiments have been reported and varying explan…
Sol-Gel Derived Ferroelectric Nanoparticles Investigated by Piezoresponse Force Microscopy
F. Johann, T. Jungk, S. Lisinski +3
Piezoresponse force microscopy (PFM) was used to investigate the ferroelectric properties of sol-gel derived LiNbO nanoparticles. To determine the degree of ferroelectricity we…
